Be careful what you Google. Really.

The Internet company will modify its privacy policy, combining 60 policies into one that will apply for all of its services, pooling data it collects on individual users across those services to better tailor search results and advertising, according to Reuters.

NPR reports some Google users are nervous about the change, which goes into effect on Thursday, given the company already collects so much personal information to produce targeted advertisements.

In the new scenario, if you are logged into an account for one of its services, Google will be able to track your activity across others. For example, if you are logged into Gmail, it can track your usage in search, YouTube, Picasa and other Google site to create a more distinct portrait of you for advertisers.
